RISVariational Data Assimilation in the Tropics Using Precipitation Data. Part II: 3D Model
Publisher: American Meteorological Society
Abstract: A global primitive equation model is used to examine the performance of four-dimensional variational data assimilation (4D-VAR) with moist processes and to assess the impact of assimilating precipitation data in the Tropics. ...
Variational Data Assimilation in the Tropics Using Precipitation Data. Part III: Assimilation of SSM/I Precipitation Rates
Publisher: American Meteorological Society
Abstract: The performance of four-dimensional variational data assimilation (4D-VAR) in the Tropics is examined by assimilating radiosonde and pibal data over the globe and Special Sensor Microwave/Imager (SSM/I) precipitation rates ...
Predictability of an Atmospheric Blocking Event that Occurred on 15 December 2005
Publisher: American Meteorological Society
Abstract: tmospheric blocking occurred over the Rocky Mountains at 1200 UTC 15 December 2005. The operational medium-range ensemble forecasts of the Canadian Meteorological Center (CMC), the Japan Meteorological Agency (JMA), and ...
The Variational Assimilation Method for the Retrieval of Humidity Profiles with the Wind-Profiling Radar
Publisher: American Meteorological Society
Abstract: Recently, a humidity estimation technique was developed by using the turbulence echo characteristics detected with a wind-profiling radar. This study is concerned with improvement of the retrieval algorithm for delineating ...
